A simple way to add UTC time zone check to ORMLite. You should initialize it with SqlServerOrmLiteDialectProvider.Instance = new UtcSqlServerOrmLiteDialectProvider(); somewhere in AppHost.cs

gistfile1.cs

    public class UtcSqlServerOrmLiteDialectProvider : SqlServerOrmLiteDialectProvider
    {
        public override string GetQuotedValue(object value, Type fieldType)
        {
            if (fieldType == typeof(DateTime))
            {
                var dateValue = (DateTime)value;
                if (dateValue.Kind == DateTimeKind.Local)
                    dateValue = dateValue.ToUniversalTime();
                const string iso8601Format = "yyyyMMdd HH:mm:ss.fff";
                return base.GetQuotedValue(dateValue.ToString(iso8601Format), typeof(string));
            }
            return base.GetQuotedValue(value, fieldType);
        }

        public override object ConvertDbValue(object value, Type type)
        {
            if (type == typeof(DateTime))
            {
                var result = (DateTime)base.ConvertDbValue(value, type);
                return DateTime.SpecifyKind(result, DateTimeKind.Utc);
            }

            return base.ConvertDbValue(value, type);
        }
    }
